T0 all whom it may concern:

Be it known that I, ERNEs'r RENAUD', a subject of the King of Great Britain, residing in the city and district of Montreahin the Province of Quebec,- Canada, have invented certain new and useful Improvements in Train-Stopping'Means; and `I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it a pertains to make and 'usethe samehis'invention relates to new and useful improvements in means desi ed for stopping trains 'of cars throughsuitable mechan-y lsm which is adapted to be operated from a station or from any suitable location along the track, which mechanism is adapted `to shut off the steam in a locomotive in case the locomotive shall pass a station or predetermined point in violation of orders or signals i rises certain fea- 'describe d, and specifically pointed out in the clailns.

The object of this invention is to provide simple, economical, .and ^durable means adapted for the purpose described which will be positively operated' when pro erly, set by the operator, as hereinafter descri bed. o

Referring to the accompanying drawin s, in which similar numerals of reference 'in' icate corresponding parts in all the views, Figure 1 is a diagrammatic plan view of a pair of railway-tracks, a station, and ground Operating devices, as hereinafter described. Fig. -2 is a fragmentary rear elevational View of a locomotive looking into the cab. F ig. 3 is a plan view of the devices connected with the present inventin which are shown fin Fig. 2. Fig. 4 is a'fragmentary side elevational view of a locoinotive equippedjwith the present invention. Fig. 5 is an enlarged fragmentary 'sectional view showing a checkvalve and an Operating-lever 'hereinafter specified. F ig. 6 is a detached broken elevational view of the weight-socket, supportings .rings, and o erating'- weight hereinafter escrlbed; and ig. 7 is a detached detail of the station-levers. i

Referring to the parts, vcommencing with Fig. 1, 1 2`are railway-tracks. 3 is a station- 4 is a platform or latefrom Whichirises the segmental rack 5, shown in detail in Fig.' 7,) a stub-shaft' 6 being Ysupported Ith'ereby and;

an operating-lev'er 7 beingcarried'iliyfsai'd;v Stzllbfhaftfi 1 Saidloperating-lever i's provided-l thrust of the rod'17a with a thumb-latch`8,-\which is adapted to release the pawl 9, said pawl being adapted to interlock `with ndtchcs` or recesses 10, formed in the perirneter of the se ment 5- to lock said lever 7 in predetermine positions. Below the shaft I6 thwlever 7 vterminates in a segmental gear 11,-wwhic`h ``ineslies with the said lower lever beingymou'ntedmpon thev stub-shaft 14, which is suitably supported in other arm 21 of said be crank lever.

17, which rod 17 iscon- -nected with the ar'm 18 of the -bell-crank le'- ver 19, a rod 20 being connected with the. l- A .sec

ond bell-crank lever 22 is connected ,to the opposite end of said rod 20, and a short'rod:

23 extends to the arm 24 `of another-bellcrank lever, which'is rockably mounted in the ground-casing 25, a push-rod .26 being pivotally connected 'at 27 with theotherarnr 28 ,of said last-mention'ed bell-crank lever, which. ush-rod 26 is adapted to be projected '30 of said ground-casing,`so th`at When the level` 7 is rocked in the proper direction the push-rod 26 will be projected into proximity with the nearer'rail of the trackl 2 or will be retra'cted into the extension 30 of the groundcase 2'5, as'may bedesired. A second plat- 4 form 31 is provided in the station 3, upon which is mounted an operatin -lever 7, which is connected in the manner s own in Fig. 7 with a lower lever 13, andfroin said second lower lever 13 extends a rod 17a, whioh'is connected with a bell-crank lever 24a, which bell-crank lever is adapted to operate a pushrod 26a in the same manner as the push-rod 26 is operated, the difference being that in the arran ement of the device shown at the right-ban side of Fig. 1 the bell-crank levers 19 and 22 are eliminated, owing to the direct in engagement with the bell-crank lever 24a, whereby said bell-crank levers 19 and 22 are rendered unnecessary.

Supported from the cab 35 is a tube 01` l holder 36, in which is mounted a rockable rod 37, which rod ,is provided ,with la'teral eX- tensions 38 and 39 at the lower and upper ends thereof', respectively, the lower end 38 being 'adapted to contact with the rods 26 Aor 26a when said rods `26 or-26a are projected to the limit of their outward Inovement. i

v orted 'a suitablefcasmg 40,1prefer- "abkly ;thin theflca of the englnais a weight 'throug the perforation 29 in the extension i ioo' IIO s 41, from which project pins or lateral exten- I 7 6', with central opening bolted to the upper side of said caseto prevent upward thrust of sions 42, which pins rest upon the upper ends of springs 43, which Springs assist in supporting said weight 41 in an elevated position, there being a stem 44, which 'is preferably rectangular, projecting upwardly from the weight 41. The weight 41 rests normally upon the lateral extension 39 of the rod 37.

Supported in any convenient man'ner within the cab, as by 'means of the bracket 46, 1s a .plunger-casing 47, in the upper portion of which 1s journaled the stem 4'8, which stem carries the arm 49, with which is connected a coil-spring 50, the opposite end of said spring being connected 4to the front Wall 51 of the cab by any suitable means,

Secured to one face of the arm 49 is a clip 52, in which is normally seate'd the upper` end of the rod 44, whereby the arm 49 is held in a relatively forward position against -the stress of the spring 50.

It is evident that when the rockable rod 37 is turned from its normal position, in .which throttle-lever 55, whichis supported in the lusual manner and carries a dog or pawl 56,

the extension 39 serves to support thel weight 41, 'that such weight 41 will drop by gravity, thereby releasi'ng the arm 49, which will be drawn in the direction indicated by the ar-.f

row in Fig. 3-that is. towai'd the front wall of the cab.

rThe engine is provided with the usual while a link or cable 62 conneots said lever vth the arm 49, before referred to, a spring 63 tending normally to hold the thumb-latch 59and lever 60 separated. Extending also from said arm 49 is a cord or cable 65, which passes over the sheave 66, which is supported as shown' in Figs. 2 and 3, said cable 65 runvsis nin r thence to the o erating-arm 66a of the air-:brake valve 67, w ereby it is evident that upon the fall of the weight 41 the throttle will be closed and the air-brakes 4will be set through the instrumentality'of the poweiful spring 50 referred to. As it is desirable to close the throttle gradually, means are provided, as shown in Fig. 5, for limiting the speed of movement of tl' arm 49 under the' influence ei' said spring'` F 'tsfollows1 Mounted upon the lower en ,ne stem 48 is a beveled 70,'which viwith a correspondingly bevcled gcu i, which is keyed 0.' pinned upon the crank-shaft 72,which crankshaft is mounted in suitablebearings 73 in said casing 47. A collarlfT is provided upon the stem 48, which collar rests upon the upper face 75 of the case 47, vthere being a clip e'ration' of the throttle-lever.

the stem 48, said cli bearing against the upper face of said co lar 44, as shown. The =lower portion of the case 47 is of reduced diameter and is provided with an inner shell 77, which forms a seat or pocket 78 for the plunger 79, which is connected, by means of the link 80, with the crank portion 81 ofsaid shaft 72. The inner Shell 77 is perforated, as' shown at a, for the passage of air, and when the arm 49 is drawn forwardly by said spring 50 the plunger 79 is forced downwardly in the pocket 78 against the pressure of the air contained therein, which air will slowly pass in the direction indicated by the arrows in Fig. 3, and will escape'through the peiforations 82 to atmosphere, thereby decreasing the speed of movement of the sald arm 49 and rendering more positive theV op- When it is desired to reset the device, the weight 41 is lifted, so that its stem 44 may become locked carry the lateral extension 39 below said wei'g'ht for the purpose of supportlng it in an Ielevated position.

The ground mechanism and station-levers, with their appurtenant connections, being placed in position in .proximity to a railwaytrack or to a plurality of railway-tracks, an operating-lever being provided for manipulating each of the push-rods in said ground connections, anda locomotive being equipped with the devices shown in Figs'. 2 to 6, inclusive, it follows that in the event of alocomotivevpassing a station eitherfin violation of orders or through ignorance of'fdanger it is possible foi` the station operator to stopthe train, if desirable,- without consulting the engineer, and this is done by merely throwing the lever-7 to the proper position to cause the push-rod 26 to `proj ect in such close proximity to the track that-the lower lateral extension 38 of the rockable rod 37 will contact therewith while the said .rockable rod 37 will be partially rotated in its socket, thereby permitting the weight 41 to drop by gravity and automatically shut ofl` the supply of steam, at the same time set- -ting the alr-brakes and effectually stopping the train. I r

VVhile I have shown in the accompanying drawings the preferred form of my invention, it will be understood that 1 do not limit myself to the precise form shown, for many of the details may be changed in form or position without afi'ecting the operativeness or utility of m i invention, and I therefore reserve the rig t to make all such inodifications as are included Within the scope of the following claims or of mechanical equivalents to the structures set forth.
